The Seamoth Solar Charger is an Upgrade Module that enables the player to recharge their Seamoth's battery while in the sun.
Applying the Seamoth Solar Charger to a Seamoth gives it almost unlimited Energy during the day in low depth.
Although these modules have a cumulative effect, they are so effective in their operating range that one module is more than enough.
Efficiency[]
The Seamoth Solar Charger recharges the Seamoth's Power Cell when exposed to sunlight. At the surface, during the day, one Seamoth Solar Charger gives 1% of energy every second. This value is lower during sunrise and sunset, which are the first and last five minutes of the 20 minute in-game day.
Seamoth Solar Charger have cumulative effects. Four of them recharge the Seamoth at a rate of 4% per second at the surface.
The power generated by a Seamoth Solar Charger decreases with depth. One module is powerful enough to charge a moving Seamoth up to 150m depth. Two are enough up to 175-200m.
Below 200m, Seamoth Solar Charger modules have a very weak charge rate, not even enough to sustain the Seamoth idle energy consumption (1% every 16s).
